LEON SAND. 
The Leon sancl is the typical soil of the scrub palmetto flatwoods, 
though it includes a hammock phase when considered from the stand¬ 
point of vegetation. The texture and structure of the soil material 
are identical in the scrub and hammock areas. It also occurs in the 
sand ponds or depressed basins. Typically the soil consists of gray 
to white medium sand, somewhat compact but incoherent where cul¬ 
tivated, 36 inches or more in depth. The gray color of the surface 
is the result of a slight admixture of organic matter. In places along 
the dontact with Portsmouth soils the surface is often dark. A char¬ 
acteristic feature of the type is the speckled or salt-and-pepper ap¬ 
pearance of the surface, caused by specks of organic matter inter¬ 
mingled with the soil grains and, to some extent, the staining of the 
soil grains themselves with organic material. Beneath the gray or 
grayish-white surface the sand is generally white, though in places a 
slightly yellowish or brownish tinge is found. There is usually en¬ 
countered within the s'oil profile of 36 inches, as a rule from about 20 
to 30 inches beneath the surface, a brown-colored compact stratum 
of sand. This material resembles coffee grounds. It is darker in 
the upper portion, gradually becoming lighter below. Underneath 
is found water-saturated white or slightly drab-colored medium sand, 
extending to the underlying limestones of the. region. The thickness 
of this compact brown layer varies from a few inches to a foot or 
more. This layer is locally known as “hardpan.” When wet it is 
penetrated without difficulty by the soil auger, but when dry it be¬ 
comes hard, and, at least in places, will obstruct the growth of the 
Foots of plants and trees. The brownish material giving rise to the 
'Compactness of the layer consists of organic matter, with some com-
